The main object of this invention is to provide a pair of gliders which are adapted to be secured to the feet of the user for the purpose of gliding over the surface medium.

Another object of the invention is to provide a pair of members which are adapted to be used as a water glider by a person standing upon them and is equipped with paddles which in the forward movement of the glider member offer no resistance to the water and when forward progress of the water glider is retarded or stopped the paddles hang in suspended position and serve as baflles to prevent the backward movement of the wa ter gliders.

The above and other objects will become apparent in the description below in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a top plan view of a pair of water gliders.

Figure 2 is a side elevational view of Figure 1.

Figure 3 is an enlarged cross-sectional view taken on line 3-3 of Figure 1, showing one of the paddles in suspended and operable position.

Figure 4 is a fragmentary enlarged crosssectional view of one of the water gliders showing the paddle and paddle guide in collapsed position.

Referring in detail to the drawings, the numerals 10 and 11 indicate the front portions of a pair of water gliders. These front portions have a curved bow 12 and are secured to rectangular rear portions 13 and 14: by hinge members 15 so that the front portions 10 and 11 may be folded over about the hinges to. rest upon the rear portions 13 and 14 respectively. At the rear end of the rear portions 13 and 14 and at the front ends of the forward portions 10 and 11 of the water gliders anchoring studs 16 are secured intermediate the width of these members. These studs have the ends of coiled springs 17 and 18 secured thereto for the purpose of yieldably retaining these water gliders in aligned and contacting positions.

To insure a rolling contact between the of a water mutually adjacent, contacting sides right H angle studs 19 "are provided at spaced-apart positions along the forward member lliand rear memberl l' of one of the water gliders.

These right angle "studs journal, rotatable "rollers 20ther'ebetweei1. .Forward the rear of the'front members '10 and 11 of the water gliders and intermediate the width thereof hoods 21;" are mounted.- These hoods are adapted to receive the front'portions' of'both feet of the user of thewater glider. I

The under surfaces of, the forward and rear members of the water glider are-provided with rectangular plates 22 which serve as paddles and are suspendedfromeyelets 28. -Theupper corners of'these paddles are extended to form projections 24 whic'h enter into the eyelets and serve as means for p'ivQ otally suspending said paddles from the water glider. Toretain the paddles in effective operating position and at an angle guides are provided behind each paddle. These guides are substantially L-shaped members 25 which have an erector shoulder 26at one end and an extension 27 at the opposite end. In company with each paddle a pair of guide members 25 are-used. The guide members are arranged'beside both end edges of the paddles and when erect as-"indicated in=Figure3 the ears27' serve as an 56 abutment for the lower corners of the paddles 22 and retain these paddles in operative'position. The-guide members 25 are'adapted to befolde'dbver and are'connected to the p underside of the Water glider members by 35 hi e The} device is designedv to permit locomotion over a liquidmedium by the user. "The operator places the front portions of his feet within the shoe hoods" -21'located at-therear 9 of'the front members 10 and11 of the water vgliderxfThe user thrusts one foot forward partly submerged with the weight of an operator thereon. When the forward thrust of the foot has been completed further movement is stopped and the paddles 22 then fall to suspended position assuming an angular outline as indicated in Figure 2. This effectively brakes the back thrust of this particular glider and prevents a backward movement while the other water glider member is being thrust forward. The coiled springs 17 and 18 on the water glider members are adapted to retain the glider members in con tacting relation to eachother. To provide a convenient method of-transporting these 16 water glider members, means are provided for collapsing the same. Therefore, each water glider member is composed of two parts, a forward and rear member which are arranged in pairs as indicated by the numerals 11 and y 14; and 10 and 13 respectively. The members 1-3 and 14 forming the rear portions of the glider members are swung about the hinge members 15 until they come to a position of rest upon the front members 10 and 11 re- 2 spectively. The erector guides are also I mounted upon hinges 28 so that these members may be folded over to lie flat upon the under surfaces of the rear portions of the water gliders as indicated in Figure 4. It is to be noted that certain changes in form and constructionmay be made without departingfrom the spirit and scope of the invention.

We claim: 7 3 1. In a deviceof the class described apair of members adaptedlto glide upon the water, foot hoods mounted upon said members adapted to receive the front portions of the feettherein, coiled springs attached to both 4 members adapted to retain said members in aligned relation adjacent to each other, rollers rotatably. mounted on the side of one of said members, said rollers being adapted to contact rotatably with the opposite memf bers, and hinged guide posts secured to the bottom of said members for limiting the movement of said paddles.

2. In adevice of the class described, a pair of members adapted to glide upon the water, 9 foot hoods mounted upon said members adapted to receive the front portions of the feet therein, coiled springs attached-to both members adapted to retain said members in aligned relation adjacent to each other, rollers rotatably mounted on the side of one of said members, said rollers being adapted to contact rotatably with the opposite mem bers, and hinge guide posts secured to the bottom of said members, said members being divided intermediate their length and connected by hinge members.

In testimony whereof we aflix our signatures.
